And for many it’s been family versus family, parents versus children, siblings versus sibling.

With an event as steeped in tradition as the annual Bell Game in a town the size of Pueblo, the high school football rivalry between Centennial and Central high schools, the lines of allegiance are well-defined.

But that line traces through bloodlines.

“My kids won’t even hug me when I wear my Central shirt,” said Mike Sanchez, one of 10 siblings who all graduated from the Orman Avenue campus.

But now, Sanchez is a social studies teacher at Centennial.

“We won’t even touch you,” one of Sanchez’s kids said as they walked to their seats for Friday’s Bell Game at Dutch Clark Stadium.

Juan Nava graduated from Centennial High School, but he taught 40 years at Central, where he still substitutes today.

He’s had nieces and nephews graduate from both schools and the family dynamic, especially on Bell Game Week, has been interesting.

“I used to have a red convertible and one year they filled the inside with newspaper, the whole inside of the car with newspaper. And they painted my engine blue and it was parked in the garage,” the 79-year-old Nava said.

“My blood is red but my heart is blue. And it’s fantastic.”

For Paul and Shirley Arriaga, their three children graduated from Central. Paul Arriaga is a Wildcat himself, but now he coaches the Bulldog’s volleyball team.

“You see what side he’s sitting on,” Shirley Arriaga said sitting on the Central side of the stadium.

One night after practice coach Arriaga brought his gym bag home and his family found a red-and-white Centennial pom-pom inside.

“We said, ‘What is this?’ ’’ Shirley Arriaga said.

“They disposed of it quickly,” her husband added.

Arguably the greatest feud this year was in the Odell family.

Zach Odell is head football coach at Central, where he became assistant principal this year.

With the promotion his wife, Tonja, who was a Central teacher, had to transfer to Centennial.

To show her support for both schools she wore two neck scarves — one with red and one with blue. Until her coach husband noticed, anyway.
